The electric eel gets its name from its shocking abilities! Special organs in the eel’s body release powerful electric charges of up to 650 volts—that’s more than five times the power of a standard United States wall socket! Although eels have the power to be the bullies of the Amazon, they are actually not very aggressive animals. The eel uses its shock to stun prey and keep predators at bay. Electric eels are nocturnal, live in muddy, dark waters, and have poor eyesight. So instead of using eyes, electric eels emit a weak electric signal, which they use like radar to navigate, to find a mate, and to find prey. Once prey is found, electric eels will use a much stronger shock to stun prey, usually smaller fish. Electric eels can grow up to 8 feet (2.5 meters) in length. Despite their appearance, electric eels aren’t actually eels at all! They are more closely related to carp and catfish. The shock of an electric eel has been known to knock a horse off its feet. Now that’s shocking!

The Madagascar hissing cockroach is all hiss and no sting. Its alarm hiss, which sounds like a loud snake hiss, is the cockroach’s attempt to scare off intruders. The male cockroach also uses distinct hisses to attract a mate and to intimidate other male cockroaches. When defending their territory from other males, these cockroaches will hiss, push, and shove, and stand on their “toes” to show who’s boss. The male that is larger and hisses more usually wins. It is one of the largest species of cockroach in the world—adults grow to be between two and four inches (5.1 and 10.2 centimeters) long! With their thick and waxy exoskeletons, Madagascar hissing cockroaches may look like big pests, but they’re actually important to the health of the rain forest. They are detritivores, which means they eat decaying plant material and animal carcasses. They recycle nutrients back into the ecosystem.

California sea lions live on the western coast of North America from the Baja California peninsula in Mexico to British Columbia. These semi-aquatic mammals feed on fish, squid, and shellfish. They are generally found in open water, where they prefer to fish, but are sometimes found in rivers near the coast as well. These sea lions are an intelligent and social species. They travel in groups of 12 or more, and hang out on man-made structures such as piers and jetties. They gather on remote sandy beaches and rocky areas to breed. During breeding season, males claim and defend their territories. Mothers usually give birth to a single pup after a gestation period of 11 months. The pups are able to swim at birth, although young pups stay on the beach rather than venturing into the water. California sea lions are usually dark brown, although some females can appear tan. Pups are born with a dark, black-brown coat. The California sea lion is faster than any other sea lion or seal in the world. They can dive to depths of 900 feet, and can stay underwater for nearly ten minutes without breathing by slowing their heart rate. Text by Sara Zeglin / NGS Staff

A luna moth perches on a leaf, its bright green wings folded over its body. Suddenly the insect spreads its wings to reveal their great size. This moth’s wingspan can stretch four and a half inches—that’s about the same length as an iPhone. CATERPILLAR CRAVINGS Found only in North America, the luna moth starts out as a very hungry caterpillar. Newly hatched, this caterpillar constantly munches on the leaves of walnut, hickory, sweet gum, and paper birch trees. After about a month of filling up on these plants, the caterpillar builds a cocoon. The insect lives inside for about three weeks, then emerges as a moth. The eye-catching critter is easily recognizable because of its wings. But that’s not the luna moth’s only interesting feature. The insect doesn’t have a mouth or a digestive system. That’s because it only lives for about a week after leaving the cocoon, and it doesn’t ever eat. BAT AWAY Although luna moths don’t have an appetite, they’re a favorite snack for bats. To protect themselves from these predators, the moths spin the tails of their wingtips in circles. This disorients the bats so much that the moths are often able to make a getaway. Guess you could say they’re winging it! Text by April Capochino Myers

Seaweed sways quietly on the ocean floor off Florida. Suddenly something cuts through the water, disrupting the calm. It looks like a chainsaw. But the object isn’t a tool that’s come to life—it’s a smalltooth sawfish. FEELING NOSY These animals belong to a family of fish that have long, flat rostrums—or snouts—with sharp teeth sticking out around the edges. Related to sharks and rays, sawfish use their rostrums to dig under the ocean floor for crustaceans such as shrimp. They also snag other fish like herring by swiping at the prey with their spiky snouts. Smalltooth sawfish mostly live in warm, shallow waters off the coast of the southeastern United States and in parts of the Caribbean Sea. (Some also live off the west coast of Africa.) They can grow 18 feet long and weigh more than 700 pounds. Despite its big size and fearsome nose, the fish is usually gentle unless provoked. And the animal has few predators. But young, smaller sawfish must watch out for enemies such as large sharks and even dolphins. RELIEF FOR TEETH If a sawfish chips a tooth while defending itself, or if its chompers get worn down, it’s no big deal. The animal’s teeth continue to grow throughout its life. This amazing fish has one jaw-dropping snout! Text by Andrea Silen / NGS Staff

Beavers are the largest rodents (gnawing animals) in North America and the second largest in the world, behind the South American capybara. Beavers are powerful swimmers that can swim underwater for up to 15 minutes. As the beaver dips underwater, the nose and ears shut to keep water out. Transparent inner eyelids also close over each eye to help the beaver see.

The beluga, or white whale, is one of the smallest species of whale. Their distinctive color and prominent foreheads make them easily identifiable. Unlike most other whales, the beluga has a very flexible neck that enables it to nod and turn its head in all directions. Belugas generally live together in small groups known as pods. They are social animals and vocal communicators using a diversified language of clicks, whistles, and clangs. Belugas can also copy a variety of other sounds. These whales are common in the Arctic Ocean’s coastal waters, though they are found in subarctic waters as well. Arctic belugas migrate southward in large herds when the sea freezes over. Belugas feed on fish, crustaceans, and worms. The whale is related to the tusked „unicorn“ whale known as the narwhal. The beluga is not related to the sturgeon of the same name, which has been heavily fished for its famous caviar.
